Porsche unveils its 'most sporting 911 yet'

The new 2010 Porsche 911 GT3 RS has been revealed in the lead-up to next month’s Frankfurt Motor Show

The new GT3 RS is fitted with the same 3.8-litre flat six as the GT3, but it has 444bhp instead of 429bhp, bumped up from 320kW to 331kW.

The latest GT3 RS gets wider tracks at the front and rear for greater grip and a huge carbon-fibre rear wing with aluminium supports.

The naturally aspirated engine is mated to a low-ratio, short-shift six-speed manual gearbox.

A lithium ion starter battery will be available instead of the standard unit, reducing the kerb weight by 10kg.

Brand-new body graphics, a hallmark of the GT3 and GT3 RS, are also featured on the 2010 model.

Porsche has yet to offer the full technical details for the latest RS, but more information will likely be made available closer to September's Frankfurt Motor Show, where it will also show the new Porsche 911 Turbo model.
